In a blender or food processor, process roasted peppers, 1/4 cup soup from pot and 1 tablespoon half-and-half until smooth. Scrape into a small bowl. Put 1 cup of the soup and remaining half-and-half in blender or food processor and process until smooth. Pour back into pot and heat until hot.

Serve soup with a swirled spoonful of red-pepper mixture in each bowl.
